The new record follows the previous benchmark of 25.26% in June, also established by LONGi.
Research and development into HJT solar cell technology is an important focus for LONGi in its commitment to lead the global energy transformation with technological innovation. The two world records set within five months of each other underline the company’s leading position in innovative high-efficiency solar cell technology and its vision to drive forward the sustainable and rapid development of the global PV industry.
